tomevault-io Skill: Security — Role Assignment and Self-Elevation
This skill uses PAC CLI exclusively. Do NOT write Python scripts for role operations.
Preview Before Running
Role grants and self-elevate are destructive (they change security posture and are logged to Purview). Before running, preview the action in plain prose — target user, role, environment(s) — using placeholders (<ENV_URL>, <USER_EMAIL>) for anything unknown, and ask for confirmation and missing values in the same turn. Skip the raw pac admin block; the user shouldn't have to read CLI syntax to approve a security change.
Key principle: the user should be able to evaluate what's about to happen from your first response. A bare "which environment?" fails that test; a one-line prose preview passes it.
Examples
Assign role (user given, env missing):
- ❌ "Which environment should I target?"
- ✅ "I'll assign System Administrator to
user@contoso.comon<ENV_URL>. Confirm to proceed and provide the target environment URL (or 'all' to list and batch)."
Admin access across all environments:
- ❌ "Please provide your email address."
- ✅ "I'll list your environments, then assign System Administrator in parallel on each one for
<YOUR_UPN>. Ifassign-userfails on any environment, I'll fall back to self-elevate (logged to Purview) for that one. Confirm to proceed and provide your UPN."
Skill boundaries
| Need | Use instead |
|---|---|
| Create or modify tables, columns, relationships | dv-metadata |
| Manage org settings, audit, bulk delete, retention | dv-admin |
| Query or read records | dv-query |
| Write, update, or delete records | dv-data |
| Tenant-level governance (DLP, env lifecycle) | pac admin --help |
Prerequisites
- PAC CLI installed and authenticated (
pac auth create) - System Administrator role in target environment (or Global/PP/D365 Admin for self-elevate)
- Active auth profile:
pac auth list
Assign a Security Role to a User
pac admin assign-user --user <email-or-object-id> --role "System Administrator" --environment <url>
Arguments
| Argument | Alias | Required | Description |
|---|---|---|---|
--user |
-u |
Yes | User email (UPN) or Azure AD object ID |
--role |
-r |
Yes | Security role name (e.g., System Administrator, Basic User) |
--environment |
-env |
Yes | Target environment URL or ID |
--application-user |
-au |
No | Treat user as an application user (service principal) |
--business-unit |
-bu |
No | Business unit ID. Defaults to the caller's business unit |
Batch Workflow: Assign Role Across Multiple Environments
Run in parallel — never sequentially:
Step 1: pac admin list -> Get all environments
Step 2: Filter by type if needed (e.g., Developer, Sandbox) -> Identify targets
Step 3: Confirm with user — show list of target environments
Step 4: Run ALL assignments in a single bash call:
pac admin assign-user --user user@contoso.com --role "System Administrator" --environment https://dev1.crm.dynamics.com &
pac admin assign-user --user user@contoso.com --role "System Administrator" --environment https://dev2.crm.dynamics.com &
pac admin assign-user --user user@contoso.com --role "System Administrator" --environment https://dev3.crm.dynamics.com &
wait
Step 5: Report summary ("Assigned System Administrator on 3/3 environments")
Important: Always confirm which environments will be affected before assigning roles.
Tenant Admin Self-Elevation (Fallback)
Self-elevation is materially different from assigning a role to another user. pac admin assign-user <other> grants privilege to someone else; pac admin self-elevate grants privilege to the caller. The risk profile and audit posture are different, so the confirmation protocol is stricter.
If pac admin assign-user fails with "user has not been assigned any roles", use:
pac admin self-elevate --environment https://myorg.crm.dynamics.com
- Requires Global Admin, Power Platform Admin, or Dynamics 365 Admin
- All elevations are logged to Microsoft Purview
- Uses the active auth profile if
--environmentis omitted
Self-elevation confirmation protocol (stricter than assign-user)
Before running pac admin self-elevate, the agent MUST:
- State the risk explicitly. Include this wording (or equivalent) in the pre-run summary:
"This grants YOU System Administrator on
<env>. The action is logged to Microsoft Purview with your identity and timestamp." - Capture a reason. Ask for a one-line reason — ticket ID, incident number, or a free-form note such as
"dev sandbox access — no ticket". Echo the reason back in the pre-run summary so the user sees what will be on the record. - Wait for an explicit confirmation AFTER the user has seen both (1) and (2). Do NOT accept a bare "yes" given before the risk statement and reason are on screen.
- Do NOT silently fall back. If
pac admin assign-userfails, surface the failure first, then offerself-elevatewith this protocol — never chain them automatically.
Flow: Always try pac admin assign-user first. admin self-elevate is the documented fallback, gated by the protocol above.
CLI fallback: If pac admin self-elevate errors out, self-elevate manually via Power Platform Admin Center → select the environment → Access → System Administrator role. All elevations are still logged to Purview. (In PAC CLI 2.6.4 the command fails with bolt.authentication.http.AuthenticatedClientException / ApiVersionInvalid because the CLI sends an empty api-version= to the backend.)
Safety Rules
- Always confirm before assigning System Administrator role
- Show the list of target environments before batch operations
- Self-elevation is logged and auditable — warn the user
